Impact of a Node mobility in two Mobile WiMAX Networks under different speeds

Mobility is important in wireless network because internet connectivity can only be effective if it is available during the movement of node. Several works have been carried out in performance analysis of node mobility in horizontal handover, but none of those is carried out in multiple networks within the same technology, So this paper analysis the performance of mobile nodes during handover in two WIMAX networks and to measure the performance there are number of parameters available like handover latency, end - to - end delay, MOS value, Throughput, Network Delay, etc. and we have used Network Throughput, Network Delay and MOS val ue which are involved in mobility management procedures
